<P>PROBLEM TO BE SOLVED: To make a joint for connecting tightening members be in common and to stably perform mounting work, in a reinforcement device for earthquake strengthening of a concrete column. <P>SOLUTION: An annular reinforcement device surrounding a concrete column 1 includes a plurality of thin and long screw reinforcements 3 (tightening members) along a side face of the concrete column 1, and joints 4. Each joint 4 has first and second metallic materials 10, 20. Each metallic material has body parts 11, 21 having abutting surfaces 11a, 21a to be abutted to the side face of the concrete column 1 and turning connection parts 12, 22. The body parts 11, 21 have screw reinforcement connection parts 11c, 21c. The turning connection parts 12, 22 are connected mutually turnably with a turning axis L as a center. The turning connection parts 12, 22 are projected to the opposite side of the screw reinforcement connection parts 11c, 21c from the abutting surfaces 11a, 21a, and the turning axis L is shifted toward the abutting surfaces 11a, 21a from an axis 3x of the screw reinforcements 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
